Getting started with open badges

So I added a bunch of content to Mozillas wiki page describing open badges. This page had very little content other than an image and some links. I really felt it needed to have a non-tech-savvy upgrade. I did my best to put getting started with open badges into more lay terms. With a few additional edits, this is what I ended up with...

Getting Started
Being on the steep side of a learning curve can sometimes seem overwhelming. And jumping into learning about digital badges is no different. If you iterate around three main concepts, and with each iteration deepen your understanding all will be good. If you have landed here without first reading the badges about page, it is suggested you go back and read what badges are all about; About Badges.

The Three Main Roles
There really is a whole bunch of technology that went into building
open badges. Particularly, when you consider that all badges need to be
confirmed as genuine and that loads of different organizations will be
issuing badges. More on this as you deepen your understanding of badges.
The first thing when developing an understanding of badges is to
consider the three main roles of; earner, issuer and displayer. And how
these three roles work together within the whole Open Badges Infrastructure (OBI).

The Earner
The earner is anyone who wants to earn a badge. And they are willing
to focus their energy and make an effort to acquire the skills and
knowledge that demonstrates their mastery represented by the badge.
Badges are everywhere, and are particularly present in our youth. Girl
Scouts can earn badges, Students in sailing school can earn badges,
Swimmers can earn badges. It is these badge systems where people prove
skills, knowledge and ability and from this they earn badges. If you
want to jump deeper into understanding the technology behind the earner
follow this link to the technical documentation of onboarding the earner.
and their Backpack
The earner will store their badges is a digital backpack. The
backpack is the online digital place where the earner can store and
manage their badges. By managing their badges they can be put into
groups or be made private and not be available for display.

The Issuer

The issuer creates the badge, figures out what skills and knowledge
are represented by the badge, and figures out how to assess (or prove)
if a person has the skills and knowledge to earn the badge. The issuer
has a lot of heavy lifting to do, this is because determining if someone
has mastered the skills and knowledge and are deserving of a badge
requires work and should be rigorous if the badge is going to hold
value.

There are may ways to assess peoples abilities and knowledge. Figuring
out effective ways to assess these is also the responsibility of the
issuer. The assessment methods used for the badges available in our
youth are proven and have considerable rigor. For example, the
assessment of the skills and knowledge to get a scouting badge is done
with well articulated criteria and assessment forms within a master -
apprentice model. Once the badge earner has proven their skills and
knowledge against the criteria as assessed by the master, they are
issued a badge. It should be noted that there are many approaches to
assessment and what is described here is only one approach. The
important thing is that the issuer needs to figure out how to assess if
the earner is deserving of the badge. If you want to jump deeper into understanding the technology behind the issuer follow this link to the technical documentation of onboarding the issuer.

The Displayer
The displayer provides the ability to display badges. This could be a
social media site like facebook or it could be your own personal
wordpress blog. The displayer will retrieve badges from an earners
backpack and display them for all to see. The groupings and permissions
around the display of badges will be determined by the settings in the
backpack. If you want to jump deeper into understanding the technology
behind the displayer follow this link to the technical documentation of onboarding the displayer.

The Technology

These three roles can be found in the diagram enclosed. The Issuers and
Displayers are obvious as they each have their own box in the diagram.
The Earner role isn't so obvious because, as a technology, the earner
becomes the backpack. You could say the Earner is holding their
backpack. From a technology perspective and an infrastructure view the
Issuer is the provider of badges, the backpack stores the badges earned
and the displayer shows them to the world.

With a close inspection of the diagram above there are a number of
boxes, lines, images, and text. All of these represent a piece of the
technology that makes up the Open Badges Infrastructure. As you learn
more about the badges technology you will become familiar with all the
elements found in the diagram. Take the time to review the diagram,
reflect upon the Earner, Issuer and Displayer roles and how they would
interact to display a badge.

One question to really get you thinking is. "How do you determine if a
badge is genuine?" Don't think about this from an open badges technology
perspective, think about it from a real world girl scout badges or
sailing school perspective. Think again, think further than if the badge
looks official... "how would you really determine if a badge is
genuine?"
